Hesperornis is an extinct genus of birds that lived
during the late
Cretaceous period
between about 89 million and 65 million years ago.
Hesperornis were flightless and aquatic. They were large, growing to
about 6½ feet (2 meters) in length. Their wings were greatly
reduced, and instead they swam using their powerful hind legs (its legs
were in fact so widely splayed out that, Hersperornis may not have been able
to stand or walk on land).
Their beaks were equipped with teeth, which would have helped them
with holding on to fish, as well as dealing with hard-shelled prey
such as molluscs and crustaceans.
Hesperornis fossils
were first found by
Othniel C. Marsh,
who also named the genus in 1872.
Fossils of these birds
are particularly found in
Kansas in the
United States,
and also in Canada,
however it is thought likely that they were quite widespread throughout the Northern hemisphere.
Hesperornis were marine birds that lived between 89 and 65 million years ago

High Quality Content by WIKIPEDIA articles! Hesperornis (meaning "western bird") is a genus of flightless aquatic birds that spanned the first half of the Campanian age of the Late Cretaceous period (83.5-78 mya). One of the lesser-known discoveries of the paleontologist O. C. Marsh in the late 19th century Bone Wars, it was an important early find in the history of avian paleontology. Famous locations for Hesperornis fossils are the Late Cretaceous marine limestones from Kansas and the marine shales from Canada. Nine species are recognised, eight of which have been recovered from rocks in North America and one from Russia. This book was created using print-on-demand technology. |
